Browser throbbers are broken. These spinning, swirling, pulsing
artifacts were a great way of indicating state back when a web page
wasn't loaded until it was loaded, and once it was loaded it didn't
need to load any more.
But the Web 2.0 blah blah has crept up on us, and I suddenly find
myself waiting for pages to load with no indication of state. I
interact with pages, wait for a response, but find myself without any
idea of whether the connection is actually working, or how long it
might take to finish the transaction.
